IPC: G11B5/73
Filed: 1982-10-22
Abstract: PURPOSE:To prevent crack and deterioration of a surface property in process of thermal oxidation by coating a flexible substrate with a non-magnetic metallic film and further with a magnetic iron oxide continuous thin film thereon.

Title: Method for detecting magnetic field
Inventor: TOYODA KAZUMI
IPC: G01R33/02
Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To sufficiently detect a magnetic field with high sensitivity while holding satisfactory linear characteristic by using a magnetic material as the electrode of a magnetic sensor, and regulating the generated magnetic field of a coil according to the magnetic field by the magnetization of the magnetic electrode by bias magnetic field and external magnetic field. SOLUTION: A high frequency power source 5 is connected between electrodes 2a, 2b, and a high frequency current is carried to an amorphous magnetic wire 3 to measure the output voltage V0 between both wire ends. A magnetic material is used as the electrodes 2a, 2b of this magnetic sensor, the generated magnetic field of a coil 4 is regulated according to the magnetic field generated by the magnetization of the magnetic poles by bias magnetic field Hb and external magnetic field Hex of the magnetic electrodes. In spite that the magnetic material used for the electrodes of the magnetic sensor, an external magnetic field can be detected with linear characteristic and sensitivity equal to an electrode formed of a nonmagnetic material such as copper under the effect of the bias magnetic field by the coil.  Thus, the electrically and mechanically stable welding of the electrode of the magnetic sensor to the amorphous magnetic element allows the detection of an external magnetic field with satisfactory linear characteristic and sensitivity even under sever environments.

Title: Continuous detector for flow rate of powder fluid
Inventor: SOGOU MASAAKI
IPC: G01F1/20
Filed: 1981-11-18
Abstract: PURPOSE:To display flow rate with slight errors continuously and to integrate  the flow rate by detecting the quantitative change in the kinetic energy of fluid  in the bend part in the mid-way of a transport pipe as the tension or pressing  force exerted upon a load cell. CONSTITUTION:The rectilinearly advancing pressure air fed to this device is compelled to change direction in the part of a bend 1, and tends to displace the bend 1 forcibly outward with a fulcrum axis 8 of the bend as an axis. However, the bend is connected at the front and rear to flexible pipes 4, 5 on the upper and down stream sides; therefore the down stream side of the bend 1 tries to escape to an outer arc side. In accordance with said movement, a suspension fulcrum 9 tends to detach from a load cell 10 and tensile force acts upon the inside of the cell 10, thus generating a strain in the detecting part thereof. When materials to be transported are contained in the pressure air, the intensity of the force pressing the bend to the outer arc side differs from that in the case of the flow of only the pressure air and therefore the magnitude of the tensile force is operated with an electronic device. Then the momentary rate of transportation and the integrated value of flow rate are displayed.

Title: Flash device
Inventor: YAMADA TAKEO
IPC: G03B15/03
Filed: 1980-12-27
Abstract: PURPOSE:To facilitate the easy insulation between metal and another metal part of a flash device, by applying a coat for insulation on the rear surface of the back metal. CONSTITUTION:An insulated coat 8 is adhered close on the rear surface of a back metal 7.

Title: Apparatus for detecting insufficiency of deodorizing capacity in deodorizing apparatus
Inventor: UMEDA ARATA
IPC: B01D53/86
Filed: 1980-12-28
Abstract: PURPOSE: To automaticaly detect the insufficent deodorizing capacity of a deodorizing apparatus in the titled apparatus such as a diazo type copier or the like, by a method wherein power consumption of a heater within a definite time is detected and the detected value is compared to a reference value.  
     CONSTITUTION: A relay 17 and relay contacts 17a, 17b are provided so as not to operate an integrator 18 until an inside of a catalyst tank is reached to set temp. after operation of a deodorizing apparatus is initiated. When temp. of the tank inside is lowered after temp. of the tank inside is lowered to the set temp. a thermostat 15 is closed to shut off current supply of a relay 16 and a relay contact 16b is closed to supply current to a resistor 19. The integrator 18 integrates voltage generated at both ends of the resistor 19 to issue output of an integrated value. When a catalyst in the deodorizing apparatus is poisoned and the deodorizing capacity thereof is lowered, generation of reaction heat in the catalyst tank is reduced and power consumption of a heater 14 is increased. Because a current supply time to the heater 14 is lengthened, the integrated value in a definite time is gradually increased and, when the integrated value is reached to the reference value, a comparator 22 issues output to operate an alarm means 24 and the insufficiency of deodorizing capacity is informed.

Title: Molding of semiconductor element
Inventor: DANIEL KABASHIN
IPC: B29C45/26
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To mold a semiconductor element reduced in the necessity of washing and having high durability. SOLUTION: A mold 40 contains lower and upper platens 10, 18 respectively having improved surfaces 16, 20. The improved surfaces are formed by implanting an implant chemical sead in at least the regions coming into contact with a molding compd. resin among the platens. Since the surface friction and wettability of the improved surfaces lower by improving the surface of the mold by ion implantation, the necessity for washing the mold is reduced. By these surface characteristics, the discharge of a molded package from the mold becomes still more easy. At the same time, since surface hardness is enhanced, the abrasion resistance of the mold is improved.

Filed: 1985-08-27
Abstract: PURPOSE:To attain sufficient reproducibility by adding a high frequency signal having a sufficiently higher frequency than that of a modulation signal, and adding a DC bias and the modulation signal to a varactor diode being a component of a frequency modulator so as to improve the linearity of the frequency modulator comparatively easily. CONSTITUTION:A high frequency signal is fed to an amplitude control section 41 comprising pin diode 411, 412 connected in opposite polarity via a buffer amplifier. Since a modulation signal whose phase is inverted through an inverter 421 and a variable attenuator 422 and which is converted to a proper amplitude is fed to the section 41, the resistance of the diode is maximum when the amplitude of the modulation signal is negatively maximum and the resistance is minimum when the amplitude is positively maximum. Then the amplitude of the high frequency signal is minimum when the amplitude of the modulation signal is negatively maximum and maximum when the amplitude of the modulation signal is positively maximum and the result is fed to a synthesis circuit. The oscillation frequency is changed depending on the amplitude of the harmonics of the higher frequency signal.
